DETAILED DESCRIPTION OF EMBODIMENTS

Below the technical solutions of the examples of the present disclosure will be described clearly and completely in conjunction with figures of the examples of the present disclosure. Apparently, some but not all of examples of the present disclosure are described. Generally, components in the examples of the present disclosure described and shown in the figures herein can be arranged and designed in different configurations. Therefore, the detailed description below of the examples of the present disclosure provided in the figures is not intended to limit the scope of protection of the present disclosure, but merely represents chosen examples of the present disclosure. Based on the examples of the present disclosure, all the other examples, which a person ordinarily skilled in the art obtains without using inventive efforts, fall within the scope of protection of the present disclosure.

Various sandbags have already appeared in related art, and these sandbags can provide basic functions, for example, being hit by users and the like, but the inventor of the present disclosure found that the actual use effects of these sandbags are not ideal.

In view of such situation, the present disclosure provides a sandbag. As shown in FIG. 1, the sandbag includes:

a bracket, a sandbag body provided on the bracket, a display screen 103 provided on an outer surface of the sandbag body, a hitting detector 102 provided on the outer surface of the sandbag body, a processor 101 and a displayer 104.

The processor 101 is electrically connected with the hitting detector 102, the display screen 103, and the displayer 104, respectively.

The processor 101 is configured to detect hitting data of a user through the hitting detector 102, and acquire network data through the displayer 104, and control displaying of the display screen 103 according to the hitting data and/or the network data.

In the above, the displayer 104 is mainly introduced into the sandbag (a first sandbag) provided in the present disclosure, and with the displayer 104, the processor 101 can be connected to Internet and carry out data interaction with a designated server, further realizing a function of downloading data from the designated server (in this situation, the displayer 104 usually is a long-distance communication module); with the displayer 104, the process may also carry out interaction with other network terminals, for example, when the network terminal is a user cellphone or other controller, the processor 101 can receive a control instruction sent by the user cellphone or other controller, further, the processor 101 can control display contents of the display screen 103 according to this control instruction (in this situation, the displayer 104 can be a short-distance communication module, for example, NH module, Bluetooth module or NFC (near field communication) module); for another example, when the network terminal is a processor 101 of another sandbag (a second sandbag), the processor 101 can receive data sent by the processor 101 of the second sandbag (the data sent by the processor 101 of the second sandbag usually is data generated by the processor 101 of the second sandbag, with the data corresponding to hitting data of a user detected by the hitting detector 102 in the second sandbag after the user hits the second sandbag, thereafter, the processor 101 of the second sandbag sends the generated data to the processor 101 of the first sandbag), and control displaying of the display screen 103 according to the data sent by the processor of the second sandbag, for example, the hitting data detected by the first sandbag and the hitting data detected by the second sandbag can be simultaneously displayed on the display screen 103 of the first sandbag, so as to realize interaction (in this situation, the displayer 104 usually is a long-distance communication module).

Through the description in the above paragraph, it can be seen that in the sandbag provided in the present disclosure, the displayer 104 is of two types, namely, long-distance communication module and short-distance communication module, and in specific implementation, the two types of modules may exist simultaneously, or also only one type thereof can exist.

As shown in FIG. 2, the bracket provided in the present disclosure may be a vertical bracket, or may also be a hanging bracket. If the sandbag provided in the present disclosure is used in an environment where the space is relatively small (for example, used at home), the bracket is preferably a vertical bracket. The vertical bracket generally can be divided into two portions, a base 203 and a central column 202 respectively. A lower end of the central column 202 is connected with the base 203, a sandbag body 201 is sleeved over the central column 202 (the sandbag body as a whole is higher than the base). In order to serve a good fixing function, the base is often provided internally with a weighting block (for example, a structure such as lead sinker, so as to enhance the stability of the base); alternatively, an adsorption structure such as a magnet or a sucking disc is provided at a lower portion of the base, so as to enhance acting force between the base and ground through the adsorption structure. Whether providing the weighting block or the adsorption structure (only one of them may exist, or both of them may exist), the purpose thereof is to enhance the stability of the base, so that the sandbag as a whole will not fall when the user hits the sandbag body. Of course, other structures may also be added to the vertical bracket on the basis of the above solution, for example, a torsion spring is sleeved over the central column, and the torsion spring is located between the base and the sandbag body.

As shown in FIG. 3, if the sandbag provided in the present disclosure is used in an environment where the space is relatively large (for example, gymnasium), the bracket is preferably a hanging bracket. The hanging bracket generally also consists of at least three portions, namely, a base 301, a supporting frame 302, and a hanging portion 303. The base 301 still mainly serves a stabilizing function, a lower end of the supporting frame 302 is connected with the base 301 and the supporting frame 302 generally is partially in an inverted L shape, that is to say, the supporting frame firstly extends upwards (forming a vertical frame, which does not necessarily extend along a direction perpendicular to the ground, but may also possibly form an acute angle with the ground), then extends along a direction parallel to the ground (forming a horizontal frame, which does not necessarily extend along a direction parallel to the ground, but may also possibly form an acute angle with the ground), thus forming the inverted L shape. The hanging portion is provided on the horizontal frame, and the hanging portion 303 may be a structure such as a connecting chain, a connection belt, or a connecting ring, etc. The hanging portion 303 serves a function of connecting the sandbag body 304 and the supporting frame 3025. In specific implementation, the supporting frame 302 can be in varied shapes, for example, two frames of inverted L shape form one supporting frame of a portal frame shape, or a supporting frame of a ring shape. In a certain situation, the supporting frame may also be in a strip shape, a lower end of the supporting frame is connected with the base, and an upper end of the supporting frame is connected with the sandbag body through the hanging portion.

Both the hanging bracket and the vertical bracket are suitable to the present solution, and only when the use scenarios are different or other use requirements are different, it is necessary to choose one from the two types of brackets, for use. Furthermore, when the sandbag provided in the present disclosure is used in a gymnasium, the bracket is a hanging bracket, at this time, the sandbag provided in the present disclosure is a sandbag used in the gymnasium. When the sandbag provided in the present disclosure is used in a private environment, the bracket is a vertical bracket, at this time, the sandbag provided in the present disclosure is a sandbag used in a private environment.

The display screen 103 provided in the present solution may be a rigid display screen 103, or may also be a flexible display screen 103 (compared with the flexible display screen 103, the rigid display screen 103 is not prone to deformation). Considering specific use situations, the flexible display screen 103 is preferred. For example, the flexible display screen 103, for example, employs a colorful flexible display screen 103 (with the display effect similar to a cellphone screen) which uses OLED (organic light emitting diode) technology and may be subject to a certain degree of bending, or may also employ an LED array display screen 103 (with the display effect similar to an outdoor LED advertisement screen) consisting of colorful LED lamps. In the above, the resolution of the flexible colorful display screen 103 is relatively high, and the resolution of the LED array display screen 103 is relatively low. The two technologies are both technologies already appearing at present, with multiple types of specific implementation, and redundant description is not made in the present disclosure.

Generally, a display area of the display screen 103 and a detecting area of the hitting detector 102 may be overlapped, may also be partially overlapped, or may also be separated (not overlapped). Considering the specific use scenario, if the display screen 103 is a rigid display screen 103, the display area of the display screen 103 and the detecting area of the hitting detector 102 (the detecting range of the hitting detector 102 is usually one planar area) are preferably separated, otherwise, the user may easily hit the display screen 103 and causes damage to the display screen 103. If the display screen 103 is a flexible display screen 103, the display area of the display screen 103 and the detecting area of the hitting detector 102 are preferably overlapped (including completely overlapped and partially overlapped), thus the area may be saved and the user experience may be improved. In specific use, a prompt image may be displayed on the display screen 103 to guide the user to hit.

Specifically, the hitting detector 102 may consist of pressure-sensing elements arranged in an array, and all the pressure-sensing elements are provided on the outer surface of the sandbag body, or provided under a surface layer of the outer surface of the sandbag body, so as to ensure that the pressure-sensing elements may detect the hitting of the user. As long as the pressure-sensing elements are provided to be dense enough, the hitting born by the outer surface of the sandbag body can be detected sufficiently. Each pressure-sensing element is configured to send a feedback signal (in the feedback signal, an identifier of the pressure-sensing element is usually carried) to the processor 101 after being triggered (hit by the user), and the processor 101 may know, upon receipt of the feedback signal, which pressure-sensing element is hit, thus knowing the hitting area.

More reasonable hitting training can be carried out with the sandbag provided in the present disclosure. The hitting training is divided into two stages, namely, displaying stage and detecting stage.

Firstly, the displaying stage is described. As shown in FIG. 4, it shows a situation where the display area is divided into a 5×5 array (the display screen 103 includes a plurality of display areas, and the plurality of display areas are preferably arranged in an array type). In specific use, for example, the processor 101 can control a (2,1) area of the display screen 103 to be highlighted so as to guide the user to hit it, or a (3,4) area may also display a highlighted image so as to guide the user to hit it. In specific operation, the processor 101 also can drive a plurality of areas of the display screen 103 according to a certain rule and order to display in sequence and in accordance with certain pace/frequency (rule), so as to guide the user to carry out continuous hitting correspondingly. For example, the processor 101 can drive a (3,1) area to be highlighted in a 1^(st) second, drive a (5,3) area to be highlighted in a 2^(nd) second, drive the (2,1) area to be highlighted in a 3^(rd) second, drive a (4,4) area to be highlighted in a 4^(th) second, and drive a (2,2) area to be highlighted in a 5^(th) second. After these several areas are highlighted in order, the user can hit these areas in sequence, further better guiding the user to carry out the hitting exercise.

Of course, in order to improve the user experience and improve the training effect, contents displayed each time may be different (not merely highlighting any more), for example, a digit 1 is displayed in the first time, a digit 2 is displayed in the second time, a digit 3 is displayed in the third time, and so on. Corresponding to the situation described in the previous paragraph, the case can be as follows: the processor 101 can drive the (3,1) area to display the digit 1 in a 1^(st) second, drive the (5,3) area to display the digit 2 in a 2^(nd) second, drive the (2,1) area to display the digit 3 in a 3^(rd) second, drive the (4,4) area to display the digit 4 in a 4^(th) second, and drive the (2,2) area to display the digit 5 in a 5^(th) second. Furthermore, the solution can be further optimized on this basis, for example, when the digit 1 is displayed, it is displayed in a flickering manner, when the digit 2 is displayed, it is displayed in a manner of moving the digit 2 from left to right, and the like, all of which belong to the contents in the display manners.

Furthermore, the processor 101 can operate in the following manner:

the processor 101 is further configured to fetch a display strategy according to an acquired selection instruction (the selection instruction generally is generated by operating a controller by the user, or generated by directly hitting the hitting detector 102 by the user), and the display strategy includes display time and display area, and one or more of the following display pattern, display color, and display manner;

the processor 101 is further configured to control displaying, according to the fetched display strategy, that a designated area on the display screen 103 displays.

In the above, the display manner can refer to a specific presentation manner of an image in the display area, for example, flickering display, highlighted display, low-brightness display, or a pattern entering the display area from left to right, and the like. The display strategies are classified into a plurality of types, for example, straight punch training strategy, hook training strategy, or combination-blow training strategy. Each training strategy further can be subdivided according to the intensity or physical conditions of the user. Generally, the display time and the display area of each strategy are not completely the same to other strategies, therefore, after acquiring the selection instruction, the processor 101 needs to temporarily fetch the display strategy (which may be fetched from a memory inside the processor 101, or may also by fetched from the server or other network terminals).

Furthermore, in a solution provided in the present disclosure, the sandbag can further include a music player. The music player is electrically connected with the processor 101, and is configured to receive a play instruction of the processor 101 and play corresponding music. In order to improve the user experience, the processor 101 may also further perform execution as follows: be further configured to fetch the play instruction according to the acquired selection instruction. That is, the played contents can be adjusted according to the user's selection, that is, the user himself/herself can select the music.

For the displaying stage, if the display area of the display screen 103 and the detecting area of the hitting detector 102 are overlapped, the processor 101 can better detect, after the user hits, a hitting quality of the user through the hitting detector 102, and the hitting quality can be calculated according to any one or more of the following parameters: hitting accuracy, reaction speed, and hitting force.

In the above, the hitting accuracy refers to accuracy degree of hitting a display area (for example, a (4,3) area) when a user continuously hits a sandbag after the display area ((4,3) area) is highlighted. Specifically, there are a plurality of calculating manners for the accuracy degree, for example, calculating by firstly detecting a position of the hitting area (generally one planar area) through the hitting detector 102, and then calculating the hitting accuracy according to an overlapping degree of the hitting area and the display area, at this time, the hitting accuracy generally is a certain specific numerical value. For example, the hitting accuracy is such relatively precise numerical value as 76% or 46%. Alternatively, the hitting accuracy may be identified by 1 or 0 or similar value, that is, the hitting accuracy can merely reflect a result whether the display area is hit finally, at this time, the hitting accuracy merely has two numerical values, that is, hit (which can be represented by 1) or missed (which can be represented by 0).

The reaction speed refers to a difference value between a moment when the display area is highlighted and a moment when the display area is hit by the user. This index mainly reflects the reaction speed or punching speed of the user.

There are a plurality of measuring manners for hitting force. For example, the pressure-sensing elements constituting the hitting detector 102 will generate, after being hit by the user, a feedback signal, wherein in addition to the identifiers of the pressure-sensing elements, the feedback signal further can carry the hitting force (for example, the hitting force can be detected through a deformation degree of a certain test structure of the pressure-sensing element; for another example, the hitting force can be detected through a depth of a limb going into the sandbag body when the user hits the sandbag), furthermore, the processor 101 not only can know which pressure-sensing element is hit, but also can know the hitting force born by the hit pressure-sensing element.

Obviously, the hitting accuracy and the reaction speed are both in positive correlation with the hitting quality, and the correlation between the hitting force and the hitting quality can be set according to the requirements of the specific use scenario (for example, requirements for practice of different boxing types should be different, and it is not always the case that bigger the hitting force of the user is, the better it is, but the user should reasonably control the force when practicing certain boxing type).

Furthermore, in the solution provided in the present disclosure, the processor 101 is further configured to detect the hitting quality of the user through the hitting detector 102, and the hitting quality is calculated according any one or more of the following parameters: hitting accuracy, reaction speed, and hitting force.

Of course, the display area of the display screen 103 may also realize the above solutions, even when the display area is not overlapped with the detecting area of the hitting detector 102. For example, if the display area of the display screen 103 displays “upper left”, it means that the user should hit an upper left area of the detecting area; and if the display area of the display screen 103 displays “lower right”, it means that the user should hit a lower right area of the detecting area. That is, when the display area is not overlapped with the detecting area, the hitting training of the user still can be assisted. However, on the whole, in order to improve the user experience, the manner that the detecting area and the display area are overlapped should be preferred.

The operation mechanisms of the displaying stage and the detecting stage are introduced in the above, and the hitting quality can be obtained through the detecting stage. On this basis, the sandbag provided in the present disclosure still can realize a plurality of applications. As described in the above, the specific applications include two types, namely, standalone applications and network applications. The displaying stage and the detecting stage introduced in the above can belong to the standalone applications. The network applications refer to applications performing interaction with other network terminals by using the displayer 104. As described in the above, the displayer 104 can be connected to Internet, so as to carry out data interaction with a designated server (of course, it may also be unidirectional data upload or data download), or it also can be the case that the use situation of other sandbag is acquired through a short-distance communication module or a long-distance communication module. That is to say, in the solution provided in the present disclosure, the processor 101 can further perform the following three functions:

the processor 101 is further configured to upload a first hitting situation to the server, and the first hitting situation includes one or more of the following: the hitting quality generated by the processor 101 of the sandbag, and the hitting accuracy, the reaction speed and the hitting force detected by the processor 101 of the sandbag. In such situation, it is mainly to realize the uploading and comparison of data, so that other users or the user himself/herself can query the data at any time. On this basis, the processor 101 can receive the display strategy generated by the server, with the display strategy generated by the server generated according to the first hitting situation. That is, the server customizes a corresponding training strategy for the user according to the first hitting situation, so that the user can do exercises better.

The processing in the solution provided in the present disclosure further can be realized in the following manner. The processor 101 is further configured to acquire a third hitting situation stored in the server, and display the third hitting situation and/or the first hitting situation through the display screen 103. The third hitting situation includes one or more of the following: historical data of the hitting quality, historical data of the hitting accuracy, historical data of the reaction speed, and historical data of the hitting force, wherein the historical data can be that uploaded by the processor 101 of the sandbag, or may also be that uploaded by the processor 101 of any one or more other sandbags. In such situation, usually a result of the present hitting and/or other historical data is displayed to the user, so that the user can make a comparison for himself/herself (comparison between the present hitting of the user himself/herself and the historical hitting of the user himself/herself), and the user can make a comparison between his/her hitting and other people's hitting, thus seeing the gap between him/her with other people.

The processing in the solution provided in the present disclosure further can be realized in the following manner. The processor 101 is further configured to acquire a second hitting situation sent by the processor 101 of other sandbag, and display the second hitting situation and/or the first hitting situation through the display screen 103, wherein the second hitting situation includes one or more of the following: hitting quality generated by the processor 101 of other sandbag, and hitting accuracy, reaction speed and hitting force detected by the processor 101 of other sandbag.

That is, the second hitting situation generally reflects the result of other user hitting other sandbag. By simultaneously displaying the first hitting situation and the second hitting situation, the user can see the gap between him/her with other people, and the interaction between the users can be enhanced.

The specific second hitting situation may be acquired through a short-distance communication module (for example, the second hitting situations sent by the processor 101 of other sandbag in the same gymnasium), or may also be acquired through a long-distance communication module (for example, the second hitting situations acquired from a sandbag which is far away therefrom).

Before acquiring the second hitting situation, generally, network connection should be established firstly, and further, in the solution provided in the present disclosure, the processor 101 is further configured to establish, upon receipt of a connection instruction, network connection with the processor 101 of other sandbag corresponding to the connection instruction, then acquire the second hitting situation sent by the processor 101 of other sandbag(s) using the established network connection.

In specific use, a user A can send an instruction to a processor of a sandbag A by hitting a hitting detector of the sandbag A, the processor of the sandbag A will send a connection request to a processor of a sandbag B, then the processor of the sandbag B will respond to the connection request, so that the two sandbags establish network connection, furthermore, the processor of the sandbag A can send the situation of the user A hitting the sandbag A to the sandbag B, and the processor of the sandbag B can send the situation of the user B hitting the sandbag B to the sandbag A; thereafter, a display screen of the sandbag A can simultaneously display the situation of the user A hitting the sandbag A, and the situation of the user B hitting the sandbag B; moreover, the display screen of the sandbag B can simultaneously display the situation of the user A hitting the sandbag A, and the situation of the user B hitting the sandbag B.

On the basis of the above solution, the present disclosure further provides a sandbag operation method, which method is applied to a sandbag. This sandbag includes a bracket, a sandbag body provided on the bracket, a display screen provided on an outer surface of the sandbag body, a hitting detector provided on the outer surface of the sandbag body, a processor and a network module.

The processor is electrically connected with the hitting detector, the display screen, and the network module, respectively.

This method includes: the processor detecting hitting data of a user through the hitting detector, acquiring network data through the network module, and controlling displaying of the display screen according to the hitting data and/or the network data.

Furthermore, the present disclosure further provides a sandbag system. The sandbag system includes at least two sandbags provided in the above, and the processor of each sandbag can directly or indirectly carry out data interaction with the processor of other sandbag.

Furthermore, this sandbag system further includes a server, and the processor of each sandbag can perform data interaction with the processor of other sandbag through the server.
